A: GENERAL
In purpose of improving shifting quality, driving performance and fuel efficiency, we have developed 5-speed automatic transmission mainly with new hydraulic control and electronic control systems. This automatic transmission features the following:

B: NEW STRUCTURE
- Low coast brake and forward one-way clutch are eliminated to reduce friction torque.
- Torque converter structure is modified to improve acceleration performance for more linearity.
- Control valve structure is modified to reduce drive torque and weight.

C: MODIFICATIONS FOR DRIVING PERFORMANCE IMPROVEMENT

1. SHIFTING PERFORMANCE IMPROVEMENT
- Structure change of control valve has realized highly accurate and responsive control system.
- Blipping control is employed to provide automatic switching of shift schedule and active shifting control in manual mode.
- A new control system is applied so that operating the paddle switch up down while driving in D range enables manual shifting and automatically returns to normal automatic shifting under certain conditions. models with paddle switch)

D: MODIFICATIONS FOR FUEL EFFICIENCY IMPROVEMENT
1. EFFICIENCY IMPROVEMENT
- Low coast brake and forward one-way clutch are eliminated to reduce friction on gear train.
- Slip lock-up range is expanded.

2. WEIGHT SAVING
- Low coast brake and forward one-way clutch are eliminated.
- Control valve is changed to two-layer type.

E: UNCHANGED MECHANISM
The following mechanisms are unchanged from the former systems:
- Oil pump
- Front brake
- Input clutch
- Direct clutch
- High & low reverse clutch
- Reverse brake
- AWD transfer system
- Transmission mount
- Transfer
